Well stacked: Organic crystals of small molecules constitute an alternative to common polymeric electrolytes (Nafion 117) and inorganic crystals that are employed as proton exchange membranes in fuel cell systems. A phosphonic acid containing hexaphenylbenzene forms a columnar supramolecular array and exhibits a high and constant intrinsic conductivity of 3.2×10⁻³ S cm⁻¹ from 120 to 180 °C under 1 bar H₂O atmosphere (see picture).

膦化六苯苯：结晶质子导体

堆叠良好：小分子的有机晶体构成了普通聚合物电解质（Nafion 117）的替代品，而无机晶体则被用作燃料电池系统中的质子交换膜。含有六苯基苯的膦酸形成柱状超分子阵列，并且在1 bar H ₂ O气氛下，从120到180°C ，具有恒定的3.2×10 ^-3  S cm ^-1的固有电导率（见图）。
